Graph the function y = |1.6x – 2| – 3.2. over which interval is the function increasing? (1.25, ∞) (3.25, ∞) (–∞, 1.25) (–∞, 3.25)

The interval over which the function is increasing is:

                (1.25,∞)

We are given a modulus function by:

From the graph of the function we see that the function is first decreasing in the interval (-∞,1.25) and then it increases continuously in the interval (1.25,∞) and goes to infinity.

     Hence, the answer is:

                   (1.25, ∞)

1. 34

2. 268

3. x=14.4
